Arizona’s desert landscape hides a surprising secret. About 90 miles north of Phoenix, water gushes from the earth at 20,000 gallons per minute, creating a lush oasis that feels worlds away from the cacti and sagebrush most people associate with the state. This is Fossil Creek, one of only two “Wild and Scenic” rivers in Arizona, and it’s home to some of the most beautiful waterfalls in the Southwest.
But here’s the thing: getting to those waterfalls isn’t straightforward. You have two very different options, and choosing the wrong one can turn a fun day trip into a grueling ordeal, or worse, a dangerous situation. Let’s break down the two main routes to Fossil Creek waterfalls: the Dixon Lewis Trail and the Bob Bear Trail.
What makes Fossil Creek special
Fossil Creek gets its name from the travertine deposits that coat the streambed. Over thousands of years, calcium-rich water flowing from springs at the bottom of a 1,600-foot canyon has encased everything in its path, creating fossil-like formations that give the creek its distinctive appearance.
The water stays a refreshing 70 degrees year-round, making it a popular escape during Arizona’s brutal summer months. The creek flows for 14 miles through lands managed by both the Coconino and Tonto National Forests, from its source at Fossil Springs to the Verde River.
This area holds deep cultural significance for the Apache and Yavapai people, who lived along Fossil Creek for generations and still recognize it as their ancestral homeland. When you visit, you’re walking through a landscape that’s been sacred to indigenous communities for centuries.
The contrast between the lush riparian area and the surrounding desert is striking. Sycamore trees, willows, and wildflowers line the creek, creating a green ribbon through the rugged canyon that supports abundant wildlife. It’s the kind of place that makes you stop and appreciate how diverse Arizona’s landscapes really are.
Dixon Lewis Trail: easier access to the waterfall
If you’re looking for the most straightforward way to experience Fossil Creek’s waterfalls, the Dixon Lewis Trail is your best bet. Formerly known as the Waterfall Trail, this is the most popular access point for good reason.
Getting there
You’ll approach from Camp Verde, not from the Strawberry side (this is a common mistake that has stranded many disappointed hikers). From Interstate 17, take Exit 287 and head east on State Route 260 for 10 miles. Between mile markers 228 and 229, you’ll see Forest Road 708 (Fossil Creek Road) on your right. From there, it’s 14 miles of rough dirt road to the trailhead.
The road is steep, washboarded, and can be treacherous after rain. A high-clearance vehicle isn’t just recommended, it’s practically essential. The Forest Service explicitly warns against relying on GPS or mapping software, as the directions are often wrong.
The hike
Once you reach the Dixon Lewis parking lot, you’ll walk about 960 feet up a dirt road to the actual trailhead. From there, it’s an easy 1-mile hike with just 128 feet of elevation gain. Most people complete it in about 20 minutes.
The trail follows the creek to a natural waterfall where visitors spend the day swimming. The path is well-marked and easy to navigate, passing through a fenced area where wildfire regrowth is visible. You’ll appreciate the tree cover if you’re hiking in summer heat.
What to expect
This is the most crowded area of Fossil Creek, especially on summer weekends. The main waterfall is beautiful, with crystal-clear water and areas where people set up chairs and picnic spots. But be warned: swimming and cliff diving near the waterfall is extremely dangerous and has led to several drowning deaths and severe injuries.
The good news? The crowds thin out significantly if you explore upstream or downstream from the main waterfall area. Fossil Creek offers miles of gorgeous water features and secluded swimming holes if you’re willing to walk a bit farther.
The parking lot has 20 spaces (22-foot maximum vehicle length) and vault toilets. During permit season, you’ll need a reservation to park here, and the spots fill up fast.
Bob Bear Trail: the challenging backcountry route
The Bob Bear Trail (formerly Fossil Springs Trail) offers a completely different experience. This is not a casual hike. It’s a serious backcountry trek that requires preparation, fitness, and respect for the terrain.
Getting there
Access is via Strawberry, about 5 miles west of town on Forest Road 708. The trailhead is at an elevation of 5,700 feet on Deadman Mesa. Critical note: FR 708 is closed just beyond the trailhead turnoff. You absolutely cannot reach the eight Fossil Creek parking lots from this side. This is hike-in only.
The hike
The trail descends 1,500 feet over 4.2 miles into the Fossil Creek canyon. That’s 8.44 miles roundtrip, and the Forest Service estimates 4-6 hours of hiking time (not counting time spent at the creek).
Here’s what makes this trail genuinely dangerous: there’s no water and very little shade for the first 3.75 miles. Summer temperatures regularly exceed 100 degrees, often reaching 110°F or higher. Once you step off the rim, you lose cell service completely.
The trail is steep, rocky, and rutted. Going down isn’t usually the problem. It’s the return trip that gets people. After spending time in the sun and creek, hiking back up 1,500 feet on an unshaded, hot trail is exhausting when you’re already tired from the day’s activities.
The Forest Service is blunt about this: “Do not attempt this trail, especially in the summertime, without being prepared for brutally hot temperatures.” Every year, dozens of unprepared visitors require Search and Rescue, risking their lives and those of emergency responders.
What to expect
If you’re prepared, the Bob Bear Trail rewards you with access to the headwaters of Fossil Creek and the Fossil Springs Wilderness. This is a remote, backcountry experience with far fewer crowds than the Dixon Lewis area.
The trail ends at the historic old dam, where you’ll find the springs themselves. The water here is pristine, flowing directly from the source. Just downstream, you can swim against the current to enter a cove where sunlight reflects off the travertine riverbed, creating an almost iridescent view.
This trail attracts experienced hikers seeking solitude and a physical challenge. It’s not for beginners, families with young children, or anyone who isn’t in good physical condition.
Permit requirements and how to get them
Here’s where planning becomes essential. From April 1 through October 1, you need a permit to park at either trailhead. No exceptions.
How the permit system works
Permits cost $6 per vehicle per day and must be obtained in advance through Recreation.gov. You cannot buy permits on-site, and you must print your 3-page permit at home. The parking pass goes on your dashboard, and the permit holder must carry the permit and be present with ID.
The permit system uses a quota release schedule. For Dixon Lewis:
- Permits available here
- 80% of permits are released one month in advance on a rolling daily basis
- 20% are released 2 days before the visit date
- All permits release at 8:00 a.m. Arizona Mountain Standard Time
For example, if you want a permit for August 4, you can first try on July 4 at 8:00 a.m. If you miss that window, try again on August 2 at 8:00 a.m. for the remaining 20%.
You can reserve a maximum of one permit per person per calendar month. The permit is for a specific parking lot (there are 8 to choose from), and you can only park in the lot you reserved.
The permit system for Bob Bear is slightly different:
- Permits available here
- Only available Fri-Sun
- Released Monthly on the 1st the month before
For example, permits for any weekend in July are available starting June 1 at 8:00 a.m. Arizona time.
Important 2026 season update
For the 2026 permit season, Fossil Creek will have some significant changes. In April 2026, the area will only be open Friday through Sunday. Monday through Thursday, the area will be closed and vehicles will be prohibited from parking at any of the lots or along the roadway. The Forest Service expects days to expand around May or June, but check current conditions before planning your trip.
Timing your arrival
You must arrive at the Highway 260 and Forest Road 708 junction by 2:00 p.m. to use your permit. The access gate to most lots closes at 3:00 p.m., though you can exit until 8:00 p.m. Arizona does not observe Daylight Saving Time, so plan accordingly.

Plan your Fossil Creek waterfall adventure
Fossil Creek offers two very different experiences depending on which trail you choose. The Dixon Lewis Trail gives you relatively easy access to beautiful waterfalls and swimming holes, perfect for a family day trip if you have the right vehicle and permits. The Bob Bear Trail provides a challenging backcountry adventure for experienced hikers willing to work for their reward.
The key is honest self-assessment. Be realistic about your fitness level, vehicle capabilities, and preparation. This isn’t the place to push beyond your limits, especially on the Bob Bear Trail where the consequences of being unprepared can be severe.
Book your permits early, respect the land and its cultural significance, pack out everything you bring in, and enjoy one of Arizona’s most unique natural wonders. The travertine formations, crystal-clear water, and lush canyon environment make Fossil Creek a destination worth planning for.
